If your serious about getting quality recordings then even just vocals and an accoustic can
be relatively expensive i think. I am guessing that it would be all about the mic you use?
Plus you might want to add effects to vocals and the guitar and they cost.
I really think Ramshackles is the right man to be talking to on this one
To get a review, give some reviews. Give and take. Simples. If that's too complicated........
